WATERFHEATING COIL FOR GAS-PLATES.

To all 111/1 om if ruf/.1] f'oyif'wrf Be il' known that l, 'ILLIAM l'owxin. a. citizen o the Vnited titulos. residing! in the city :1nd count.)7 of hvu lrznwisro. ule of Aulilorniai` have invented :i new und useful lniprovenwnl in lVuter-Iflezdinf!

'My invention relnles'to water heating wils for gms plates wherein :i coil is retziinei'l within suil'ahle openings provided within the spider or rndizll arms that :ire provided on the gus nlzite for the support of the uten sil that it is ure. first. to provide simple and 'effective )nouns for heating water :fron'i the fiarne that is heingf used for cooking purposes on a gas plate. :ind second, effective means for retaining the coil above the lznrner in such a manner that 'the seid coil will not prevent the heat from reaching' the bottom ofthe cooking utensil on the spider or radial arms.

For a full romprehension of in v invention,

should 'he had to the nrcomimnyreference speer ing drawings forming a part of this lirution in Whichf Figure 1 is n plan View of n gas plate with my device applied thereto. Fig. 2 is n vertiffzil section taken on line X--X of Fig. 1.

The numeral l is used to designate the frame of :1. ,fins plete having radial arms Q provided in the upper edges thereof with the semioireular openingslQ. A frame 3, adapt ed to Coincide with the upper surface of the frame 1, hiiving radial arms 4 with semieir- 'cular openings 4 in the lower edges thor-enf rests on the top m the frame l in such a manner that the openings 2 .find 4 coincide :ind form eireulnr openings or apertures in which the coil 5, for the circulation oi the wider to be heated, isretziined. One end of the coil is turned downwnrdlX/f through the central opening in the circular' hinner T and lhe other end is turned downwardly between the. radial arms 2 and Il and then, turned towardthe hack of the. frame l.
